Slot Details

Siren Song is a video slot with five reels and three rows with 25 pay lines. Wins are awarded for connecting three or more symbols from left to right on adjacent reels along a pay line. Dare to resist the fatal lure of the beautiful Sirens from 0.25 credits to 50 credits per spin in a stormy, super high volatility game with a hit frequency around 1 in 3 and an RTP of 96.33%. Siren Song also comes with a bonus buy for 127.6 times your stake with 96.37% RTP.

Daylight shimmers out of reach just below the waterline creating perfect Siren feasting depth after luring sailors to their doom with their beauty and song. The reel design is opaque and doesn’t frame the play area, making for a more immersive feel. Watery effects and creepy music with dramatic scores complete the atmosphere of Siren Song which is themed intricately well.

The pay symbols start with the low card royals J, Q, K and A, awarding up to 4.2x your stake for five of a kind. The Sirens accessories make up the mid payers with a Comb, Dagger, Mirror and Shell, paying up to 28.8x your bet for five of a kind. A Harp plays the highest paying symbol awarding up to 60x your stake for 5 of a kind. The Sirens in silver, crimson and emerald play as wilds in the base game, substituting for all symbols except for scatters and will nudge to cover the full reel when landing. Silver orb scatters are found on reels 1, 3 and 5. Landing three or more of these will award a choice of bonus.

Siren Song also has two feature-only symbols; sticky skull wilds are a feature of the Emerald Free Spins and appear as the Pirate Captain and skeleton version, paying up to 60x your stake for five of a kind. Silver-coloured fish symbols pay up to 30x your bet for five of a kind during the Silver Free Spins.

Siren Song Slot Features

TrueLab belongs with the new and cool slot brigade of designers carving titles with clever gameplay and skillfully crafted graphics to stand out in casino lobbies. Siren Song adds to their menu of intriguing and colourful titles, so let’s see how alluring these Sirens can be.

Initially, Siren Song seems like another game made for a bonus buy as the fundamental gameplay has no wilds or extra features. Instead, the Siren Wilds bring a feature critical to its appeal, breaking up the play whilst hunting for scatters. When one of the Sirens appears, they will nudge until filling the reel and act as a wild substituting for all symbols.

Landing three scatters on reels 1, 3 and 5 awards eight spins from your choice of three different free spin rounds, with no retriggers but each with a unique feature and different volatility.

TrueLab Siren Song Pick 'n' Click bonus

Reels 1, 3 and 5 feature keys on the reels for the Crimson Free Spins which is billed as the low volatility bonus. Keys appearing on the reels for each spin add to a counter and total at the end of the round, awarding the amount collected as picks for the Crimson Pick ‘n’ Click bonus game. Ten chests contain random bet multipliers of 1, 2, 3, 5, 8, 12, 20, 50, 100 and 500. One chest will always contain a bonus round multiplier which will multiply any remaining picks by 2, and another chest is set aside for 1, 2 or 3 extra keys/picks. Simply pick the chests for instant cash prizes totalled at the end of the round.

During Emerald Free Spins, the medium volatility option, Skull Wilds become sticky for the duration of the round. Sticky Skull Wilds rest on the reels in skeleton form, animating to the Pirate Captain when sticking in place for the remaining spins. These wilds substitute for all symbols during the Emerald Free Spins.

The Silver Siren throws 4 to 20 fish symbols at random in the play area for the Silver Free Spins which is the highest in volatility. Two fishes thrown in the same position will create an x2 symbol, three will make an x3 fish and so on. Fish symbols connected in a line will pay up to 30x your stake for five of a kind. However, fish multipliers times each other for the win, e.g. an x2 fish and x3 fish = 6 times the line win.

TrueLab Siren Song Steering Wheel of Fortune

The grand finale of each and every free spins bonus comes with a spin of the Steering Wheel of Fortune; a chance of winning x5, x10, x25 and 100 times your stake or even multiply your sum of winnings for your chosen free spins by x2, x3, x5 or a mouth-watering x10. The wheel spins from a push of a ghostly skeletal arm and will come to rest on your final cash prize or total round multiplier, adding to your final total or multiplying your winnings.

Final Verdict

Siren Song is visually impressive and well-produced with some enormous potential capped at 30,000x your stake. A mixed volatility choice of free spins is one of the games best qualities and may seem even more attractive to bonus buy players.

The features felt somewhat stifled in our limited demo play, possibly an allowance for the Steering Wheel of Fortune at the end of each round, volatility or perhaps just our luck. Still, the wheel can turn a poor bonus into a satisfying one. And while the Siren Wilds are an irresistible attraction, their presence felt vacant.

However, our limited experience is just that and our opinion should not be used as a benchmark for authentic play. Overall, it was a pleasurable experience, being lured to impending doom on Siren Song.
